Wolf and pup poem

I had found a wolf poem for two voices (I think) It was really cute. A dad wolf was talking to his son and it went back and forth. At one point the dad tell him to stop chasing his tail and the pup says, "But dad, it's moving!" and "But dad, it's fun!"

From this very vague description does anyone know this poem or where I might find it? Thank you so much!
